On another fairly quiet day in the National Park Playoff, the biggest question was which southern Utah park join Zion in the Sweet Sixteen: #4 Bryce Canyon or #5 Arches? After a seesaw battle that was usually tied, the answer was Arches, by an 11-9 margin. That was as close as anything got on Saturday, with the other end of the spectrum manifesting in the tournament’s first shutout, where #4 Acadia blanked #5 Cuyahoga Valley 18-0. The other two matchups found more luck for five-seeds, with #5 Mount Rainier edging #13 Redwood 11-6 and #5 Badlands dumping #13 Voyageurs 15-4. After a day off, Arches will take on Grand Canyon in the Southwest on Monday, while Acadia gets Great Smoky Mountains, Mount Rainier draws Yosemite, and Badlands faces Yellowstone.

Predictive brackets closed the Second Round with a 59% accurate day and a 60% overall rate of prediction across the Round. Four brackets were perfect on Day 12 and just one went 0/4. Missed picks were most frequent in the Pacific, where six chose Redwood and four picked the eliminated Death Valley. Next was the North (five Mt. Rushmore, two Voyageurs, one Craters of the Moon), followed by the Southwest (four Carlsbad Caverns, three Bryce Canyon, one Great Sand Dunes), and the East (three Biscayne, two Cuyahoga Valley).
